Is lagfix safe for Asus Nexus 7? - Nexus 7 Q&A, Help & Troubleshooting

My Nexus 7 is starting to lag. Is "lagfix" (fstrim) safe to use on an Asus Nexus 7?
I should have added that this is a rooted Nexus 7 using stock 4.2.2.
Thank you.

I don't see why not.
Should be fine, Fstrim isn't a device specific thing, it's an OS specific thing.
Since you are running stock, you should be fine.
Do a backup to be safe.
Peace,

Works fine on mine (ParanoidAndroid).

Thank you both. I asked because of the warnings that come with it..
I used it and it got rid of my lag.
One related question if I may. The default setting (which I used) does not include /system. Would that be because it is dangerous to use it on /system?
Thank you again.

I also can confirm that it work fine on my nexus 7 too.

It might be, but since /system is "read only", there wouldn't be much point to doing an fstrim on it in any case.

Thank you. Interesting and explains why /system is not selected by default.

[Q] Update 4.1.2 to 4.2.1

I bought nexus 7 yesterday and it came with Android 4.1.2. I tried to upgrade but when installing android is laying down and there is a red triangle on his chest. I tried to upgrade more then 5 times but everytime result is same. I don't want to root.So How can i upgrade?
Before opening new thread, i search it on internet and here. But i can't find the solution. If i broke the rules , i am sorry and i am sorry my english too.
Right at the top of this forum is a guide on returning to stock. Follow that guide and it will help you get 4.2.1 running.

Apparently, some Nexus 7's were not formatted correctly, and the update notices this and flips out (I'm not claiming this as fact, just what I have read). Once you follow the above guide you should be fine though as it re formats everything. I had the same problem and everything worked for me.

[Q] What is busybox and what does it?

I rooted my nexus 7 with WugFresh nexus toolkit. Afterthat I saw the app busybox. So I would like to know if I can unistall it because I do not want to flash anything, I only what root permission for my PS3 controller.

Devices: Nexus 7 - Rooted with stock OS
Busybox contains common Linux commands/utilities that android does not have built-in. Many apps that use root will make use of busybox. If you are using any root apps its best to keep it. I guess you could have Googled that yourself in the time it took me to write it!
Ofcourse I googled it but couldend find anything

İ always wondered this myself and Scott doyland did a very good job at explaining it. It's used by apps that require root! Great piece of information!
Sent from my Nexus 7 using Tapatalk HD
I was told it was necessary for Root. I have a S3 and it was installed automatically as well.
I don't think the OP needed to be slammed by IAMNICE for his Google searching skills. Internet tough guy talk is sort of gæ.

Q Native Linux Installer

If I use the native Linux installer to put Ubuntu on my new n7 will i lose android permanently or can I revert back to android if I don't like it?
Sent from my Nexus 7 using Tapatalk 2
You can revert back. It's explained on their site (Ubuntu's Wiki for the Nexus 7 Installer).

I don't see why not. I'd backup your ROM, then copy your backup to your computer (or entire internal sd), install Ubuntu for N7. To revert, reflash factory images and re-root, flash recovery, wipe and restore backup.
I'm not sure if it wipes out your recovery or not, I am assuming it does.

Why root the Nexus 4

So I have my Nexus 4 I love it and everything is running well but I miss some of the advantages of having root. What are the biggest advantages of rooting the Nexus 4 what are the disadvantages? Can I gain root without unlocking the bootloader? I rooted only the Optimus V from virgin mobile is it all basically the same? Is there any known way to root without using a computer? Thanks for any input or suggestions you may have. it is really appreciated.

You can:
1. Install custom kernels and custom roms. (So you're telling me you only rooted the Optimus V and never installed kernels and roms?)
2. It's a different root method than the Optimus V.
3. You MUST unlock the bootloader to gain root access. Might as well unlock it. You won't needing it much unless you brick it somehow.
4. You need to root using a computer. It's not like the Optimus V, there is no special application to use to gain root.
5. The only disadvantage is you not taking advantage of it.
Here are two useful toolkits you can use to root the N4. It's very easy but if you know how to use fastboot then go right ahead.
http://forum.xda-developers.com/showthread.php?t=1766475
one very big advantage of rooting is being able to install Adaway. Adaway is an app that removes ads from any other app and browser i think? that you download. If you play games like words with friends, adaway removes the ads and makes it more enjoyable to play.
The deal breaker for me is titanium backup. I used it to migrate /restore my data from my old phone. Now I know there are other apps that can do it without rooting but titanium backup is a one stop centre.

You'll have to revert back to stock to receive them. Or you can wait till a deodexed/odexed stock rom comes out.
For me rooting it is the only way to go. I wouldn't own a server without root and I see android in the same way.
Titanium Backup
Overclock and undervolt with a good kernel like Franco to save battery
AdAway
I would have to recommend going beyond just root and installing a custom ROM.
Being able to have 5 buttons instead of 3 is pretty nice. Xylon G+
Calibrating the screen requires root. Nexus 4 Display Control
I double tap my screen to turn it on. Touch Control
You can adjust the DPI essentially turning up the resolution.
I can't really see any reason not to root / ROM other than fear, as if you go with stable reliable ROMs, you're not gonna break anything, just don't run Antutu, I hear it red light bricks the N4.
One word
PIE
(assuming you'd flash a rom after rooting)

ok.. think I want to do it... just worries me as no rom i used on the Optimus V worked 100 percent

No. You need to unlock bootloader then root. That's the order to root the device. Unlocking the bootloader will erase everything on your phone.
This is a nexus device, most roms work very well and are on par if not better than stock.

I agree.
I had the Optimus V like two years ago. I really liked that phone because it had awesome battery life. But the development was total crap. There was either little or no work done on it. The software was just mediocre.
The roms and kernels in this forum are quite mature and perfect for daily use.

Download the program now and do the following.
Here's a video tutorial.
Please watch it first and get a feel of it first!
If you follow the tutorial, you should be fine. Do not miss a step. Most folks miss a step and they panic.

I know it's a Nexus 7 video but it's essentially the same for the N4.
And this is the Nexus 4 tutorial if you don't want to use the one above.

I'll probably be installing this as soon as my tablet gets in, seeing how well my phone (d2can; running d2att) has been taking CM10.2. I'll let everyone know how it goes.
Sweet. Thanks for letting us know. I'm flashing it right now =)

You have to move your tiBU folder onto legacy/ from 0/
Look at my screenshot. Go to Preferences and set your backup folder to this location... Minus the /!Ready2Flash/TitaniumBackup part. That's my personal folder location.
